摘　　要：在自动化生产过程中安全联锁系统(SIS)被广泛使用;传统的安全联锁系统主要由逻辑电路或PLC实现,当联锁关系发生变化时需要对系统进行重新设计,影响正常生产;针对上述问题提出一种基于图的可重构安全联锁模型,该模型可以实现联锁关系的自由配置和在线修改,适合复杂多变安全联锁系统的设计,在某大型科研装置中得到成功引用,取得了良好效果。Safety Interlocking System is widely applied to Automation production. The traditional SIS is designed based on PLC or Logic Circuit commonly , which must be designed again When the control logic of SIS changes. A new system of SIS based on graph is designed, by which the the control logic of SIS can be reconfigured online expediently. The successful application results of a certain scientific research equipment show that this method is suitable for the complicated and variable Safety Interlocking System.
